Description
The 990-05-50-02-00 Vibration Transmitter converts vibration input from a 3300 NSv Proximity Probe into a 4–20 mA proportional signal for automated machinery control systems. Designed for small pumps, motors, and centrifugal air compressors, the 990-05-50-02-00 supports system lengths of up to 5 m (16.4 ft) and provides a linear measurement range of 0.25–1.65 mm (10–65 mils) peak-to-peak. The transmitter operates on +12 to +35 Vdc with a maximum loop resistance of 1,000 Ω and includes non-interacting zero and span potentiometers for easy loop adjustment. Its potted construction and bulkhead or DIN-rail mounting options allow installation in high-humidity environments and tight spaces. The 990-05-50-02-00 also features a test input for quick signal verification, a Not OK/Signal Defeat circuit to prevent false alarms, and a PROX OUT BNC connector for vibration diagnostics, making it suitable for compact automation setups requiring precise vibration monitoring.
Applications
Monitor Compressor Vibration
The 990-05-50-02-00 receives input from a 3300 NSv Proximity Probe and converts vibration data into a 4–20 mA signal, enabling real-time vibration monitoring on centrifugal air compressors.
Measure Pump Shaft Movement
With a linear range of 0.25–1.65 mm (10–65 mils) and peak-to-peak signal output, the 990-05-50-02-00 allows precise shaft displacement measurement for small pumps and motors, supporting automated protection systems.
Integrate with Control Systems
The transmitter’s non-interacting zero and span potentiometers and standard 4–20 mA output simplify integration with PLCs or DCS, allowing the 990-05-50-02-00 to provide continuous vibration feedback for control logic and alarm systems.
Support Compact Automation Installations
The 990-05-50-02-00 accepts 5 m extension cables and works with tight installation spaces, making it suitable for machinery with limited clearance, including small electric motors and fan units.

Competitive Advantage
Direct 4–20 mA Vibration Output
The 990-05-50-02-00 converts signals from a 3300 NSv Proximity Probe into a proportional 4–20 mA output, eliminating the need for additional signal conditioning and enabling immediate use in control loops.
High Humidity and Harsh Environment Tolerance
Potted construction allows the 990-05-50-02-00 to operate in 100% condensing humidity conditions while protecting the transmitter electronics.
Quick Verification and Fault Prevention
Test input pins and the Not OK/Signal Defeat circuit of the 990-05-50-02-00 allow rapid loop verification and prevent false alarms from loose probes or faulty connections.
Flexible Mounting Options
The 990-05-50-02-00 provides DIN-rail clip or bulkhead mounting, simplifying installation in constrained or modular automation setups.
